Sunscreens stop harmful ultraviolet light
from penetrating into your skin and they work in one of two ways. Some of them
absorb (soak up) the ultraviolet light. Other suncreens work by reflecting UV light
away from your skin using chemicals like titanium dioxide and zinc
oxide. When it
sits on your face, it works like a natural mirror that bounces away the harmful
energy in sunlight so it does less damage to your skin. For reflective
sunscreens to work properly, you need to apply them liberally and leave them
forming a barrier on your face and body—in other words, don't rub them into your
skin but let them dry on top, even if it makes you look like a ghost!
